    Brightness drops to 10% after upgrading to W8 (Intel HD 3000)

    Stefaan Leleu

      Hi, I recently upgraded my laptop to Windows 8. The day after the brightness suddenly dropped to 10%.


      After adjusting the slider back up, the brightness immediately drops to 10% again. With some luck the brightness may not drop back down to 10% for a few minutes. But usually it's a matter of seconds (or even immediately).


      Windows says the Intel HD 3000 drivers are all up to date.


      The problem occurs on different networks (at university, at home,...)


      Is there a solution to this problem??
